i386 version does not have Networking active. I tried on 3 different products and none worked with 4RC2. My login issue was only under one VM so that was an abnormality so nothing to worry about there. I tried the 64bit version and Networking is functioning properly there.

Oh there is one issue outstanding for me that I wanted to see if it would be fixed for RC2. That is Virtual Box does not run under V4RC1 for i386. I am not by the PC that has Virtual Box installed but it errors when you try and run it. If you don't have a i386 PC around running V4RC1 I can get the errors and post them here.
